BMI Calculator
BMI (Body Mass Index) is a simple way of comparing your weight to your height.
This calculator is designed for adults aged 18 and over.
You should not use this calculator if:
- You are under 18 years old
- You are currently pregnant
- You have a condition that significantly affects your height
BMI is only a guide and cannot tell the difference between muscle and body fat.
You'll need:
- Your height
- Your weight
BMI is a screening tool and not a diagnosis. It does not distinguish between muscle, body fat, age, sex, ethnicity or overall health. If you have concerns about your weight or health, speak to a healthcare professional.
